Appearance:

Small, stout, unmistakable raptor with pale grey plumage. Strikingly broad wings and short tail. Large, round, owl-like head with black "mascara" and short neck. Underside of wing-tips, and upper median and lesser coverts black. Immature birds often with rusty underparts and white fringes to flight feathers and scapulars. Glides with wings raised high like a harrier. Frequent and skilfull hovering.

Sound:

Not very vocal. A soft "Pjuu-harrr". Starting as a mellow, ascending whistle and ending with a harsh screech. Also uttered without the harsh ending, or only a Barn Owl-like screech. Other sounds: rapid series of soft "kekekekekekekekeke" and short whistles.

Appearance:

Forked and fairly long tail. Clearly bigger than Storm Petrel, with more slender appearance and longer wings. Generally not as black, and shows brownish tone to plumage. The white rump patch is oval, has a weak grey center stripe, and does not reach as far down on the sides as in Storm Petrel. Light grey upper greater coverts form a wing-band. Underside of wings all dark. Flight pattern variable, with frequent changes in direction and speed. Sometimes glides like a shearwater but at other times shows surprisingly deep wing-beats. Does not patter surface, but will rest on water. Visits breeding ground only at night, and is usually only seen after storms.

Sound:

Only calls at breeding ground. A series of accentuated cooing, interrupted by a squeaky "inbreath" and a loud, absurd, fanfare-like "kaaa-ka-ka-kaaa-ka".
